This guide names each agency, where its records page is and what the Iowa Open Records Law (Chapter 22) requires of it.

Which Agency Holds a Report from Linn County
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
In Linn County that is the Linn County Sheriff's Office for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
The FBI's list also places Eastern Iowa Airport Public Safety in Linn County; a report taken on a state highway by it comes from that agency's own records office.
